Multi-ringed separator for tubular organs

Abstract

A multi-ringed tubular organ separator includes a first arm having a handle at a rear end and a second arm having a handle at a rear end and combined with the first arm for rotation about a pivot into an opened position and a closed position. The first arm and the second arm are provided at their front ends with main clamps cooperating to define a main clamping zone in which a tubular organ and surrounding tissues of a mammal can be enclosed. The first arm and the second arm are further provided with sub clamps formed adjacent to the main clamps and cooperating to define a sub clamping zone in which the tubular organ and the surrounding tissues can be enclosed in isolation from the main clamping zone, the main clamping zone remaining in communication with the sub clamping zone through a throat.

1 . A multi-ringed tubular organ separator comprising:
 a first arm having a handle at a rear end; and   a second arm having a handle at a rear end and combined with the first arm for rotation about a pivot into an opened position and a closed position,   wherein the first arm and the second arm are provided at their front ends with main clamps cooperating to define a main clamping zone in which a tubular organ and surrounding tissues of a mammal can be enclosed, the main clamps having round contact portions at their distal ends, the round contact portions adapted to make contact with each other when the first arm and the second arm are closed,   wherein the first arm and the second arm are further provided with sub clamps formed adjacent to the main clamps and cooperating to define a sub clamping zone in which the tubular organ and the surrounding tissues can be enclosed in isolation from the main clamping zone, the main clamping zone remaining in communication with the sub clamping zone through a throat.   
   
   
       2 . The multi-ringed tubular organ separator as recited in  claim 1 , wherein the main clamping zone and the sub clamping zone are divided by ridges formed at a boundary between the main clamps and the sub clamps, the ridges spaced apart from each other to define the throat between the ridges, the ridges having sharpened tips for helping the surrounding tissues to be stripped from the tubular organ. 
   
   
       3 . The multi-ringed tubular organ separator as recited in  claim 1 , wherein the throat has a width smaller than a diameter of the tubular organ so as to allow the surrounding tissues alone to be moved through the throat, the ridges having flat inclined surfaces for restraining escapement of the surrounding tissues from the sub clamping zone to the main clamping zone. 
   
   
       4 . The multi-ringed tubular organ separator as recited in  claim 3 , wherein the main clamping zone is of a circular shape and the sub clamping zone is of a generally elliptical shape. 
   
   
       5 . The multi-ringed tubular organ separator as recited in  claim 3 , wherein the main clamping zone has an area greater than that of the sub clamping zone. 
   
   
       6 . The multi-ringed tubular organ separator as recited in  claim 3 , wherein the sub clamping zone has a recess at a rear part, which serves as a spare space. 
   
   
       7 . The multi-ringed tubular organ separator as recited in  claim 3 , wherein each of the tips of the ridges has a convex shape when viewed from the main clamping zone. 
   
   
       8 . The multi-ringed tubular organ separator as recited in  claim 1 , wherein each of the main clamps and the sub clamps has a convex inner cross-sectional surface and a convex outer cross-sectional surface, the inner cross-sectional surface having a curvature smaller than that of the outer cross-sectional surface. 
   
   
       9 . The multi-ringed tubular organ separator as recited in  claim 8 , wherein the outer cross-sectional surface is of a semicircular shape. 
   
   
       10 . The multi-ringed tubular organ separator as recited in  claim 1 , wherein the first arm and the second arm are further provided with additional clamps lying adjacent to the sub clamps to define an additional clamping zone.
